While there is a considerable literature on infrastructure development for the different modes, there has been relatively little research and literature on the ways in which national governments carry out their responsibilities for nation-wide regulation and governance of transport.
However, with technological developments dramatically changing the nature of "channel" within mode, there has been a blurring between what's public — traditionally negotiated in 'exploring' contexts, and what's private — traditionally negotiated in 'sharing' contexts (see e.g. Macnamara 2010; Shirky 2010).
The inked AFM tip is most commonly scanned across the substrate in contact mode, however, there have been reports of the AFM tip being scanned in tapping mode [46, 47] to form nanopatterns.
In conclusion, over the 30 years since the mode's inception there have been no strict criteria in defining a mechanical breath as being APRV.
Since Silk first came out of stealth mode in 2011, there have been 300,000 interactive pages created on its cloud-based, web data-crunching platform designed for non-technical "knowledge workers".
Even if every existing infinite mode necessarily exists, could there have been other infinite modes as well?
Alternative possibility 2 (AP2): For at least one individual member of the collection of actually existing modes, there could have been a different mode existing in its stead.
Because of these experiments, the startup has essentially been in prolonged beta (or stealth) mode, so there hasn't been much in the way of a public product.
Currently, intravenous dosage is not 'approved' by the US Food and Drug Administration, but the drug is commonly given by this mode, and there has been a broad range of experience with it in the peer-reviewed medical literature [ 45*, 46*].
6. Coolest mode of transport you've taken: There have been some interesting river crossings.
